Wan 2.2 5B trashy video quality?

[fcore117]

Is it my mistake or something other wrong, i even cranked steps up and added extra options, but still garbage video comes out. Text to image mode tested, i have not tested img-to-video mode.

Looks about right to me. What I do instead is use the fastwan finetune. It's not only faster (distilled) but also looks way better.

also feel free to try the tiny vae decoder to save vram #937

Not used by 5B.

Also try smoothstep and simple schedulers.

Or try lcm scheduler with fastwan. At 3 steps they all look very similar.

Here is what I can manage on 8gig vram in 30sec:

$ result/bin/sd-cli -M vid_gen --diffusion-model models/wan/Wan2_2-TI2V-5B-FastWanFullAttn-q8_0.gguf --tae models/wan/taew2_2.pth.1 --t5xxl models/wan/umt5-xxl-encoder-Q8_0.gguf --cfg-scale 1 --steps 3 --sampling-method euler --scheduler lcm -v -H 480 -W 832 --diffusion-fa --offload-to-cpu --video-frames 72 --flow-shift 3.0 -p "a lovely cat" --vae-conv-direct

Thank you both of you. Now seems it starts to work.

Both of me, yes 😆 . The second one should have been a comment on the first one, but I f*ed up I guess.

You should try first frame image inputs (-i), they help a lot with this model.

I have plan to move into img2img generation that's why i use dual model. I wonder is there some Wan 2.2 that makes even better quality, but in same time fits into my 12GB VRAM mostly(rtx 4070). I would not mind double encode time, juts not a slow as snail. if there is some i would be grateful for exact model combination that do not fail. Sys ram is 64GB.

I am beginner in this local AI stuff, but i chose stable-diffusion.cpp as it is better and more compact and lighter and .cmd scripts are good for me personally. I do not like those "fat" Python programs.
